Issue/Introduction

When attempting to move a VM between vApps the operation fails with:
MigrateException: MIGRATION_FAILED_DESTINATION_RESOURCE_RECONFIG_FAILED at com.vmware.ssdc.util.LMException.wrap(LMException.java:135)

In the logs there will be a specification that this is due to a null pointer exception:

Environment

VMware Cloud Director 10.6.0.1

Cause

There is a resource pool missing from vCenter that is expected that is associated with the virtual machine in the database.

Resolution

We will need to SSH into the primary VMware Cloud Director cell and perform the following steps from the docuementation: https://techdocs.broadcom.com/us/en/vmware-cis/cloud-director/vmware-cloud-director/10-6/vmware-cloud-director-service-provider-portal-guide-10-6/vcd-cell-management-tool-reference-admin/cmt-detect-rp-mismatches-admin.html

After the mis-match is corrected the error should no longer appear. If it does engage VMware By Broadcom support.
